Statistics
Variance Calculator
Compute population or sample variance from the sum of squared deviations and the sample size. The fundamental measure of how spread out a dataset is around its mean, and the building block of standard deviation, ANOVA, and most parametric inference.

Statistics
Mean Calculator
Compute the arithmetic mean (average) of any comma-separated list of numbers — the most common measure of central tendency in statistics. The result is the sum divided by the count, equivalent to balancing a see-saw of the data points.
